The Rugby Football Union has launched a review of last weekend's Championship fixture between Leeds Carnegie and Plymouth Albion.
The game, won 34-16 by Leeds, went to uncontested scrums after just 13 minutes. It is understood that match referee Matt Carley made the decision after early scrums collapsed when Headingley Carnegie's new £1million pitch began cutting up.
In a statement, the RFU said: "The RFU is reviewing the circumstances that led to the RFU Championship fixture, Leeds Carnegie v Plymouth Albion, on Sunday January 6 moving to uncontested scrums after 13 minutes of play. A statement will be made in due course."
